MACHINE FOR STAMPING OUT MOLDS. I

Application filed May 31,

The object of my invention is to provide a novel machine for pressing or stamping out molds of thin sheetmetal. I attain the objects of my invention by the device illustrated in the accompanying drawings in which Figure 1 is a perspective View of my ma chine;

Fig. 2 is an end elevation of same with a sheet of metal inserted ready to be pressed into the desired shape for use as a mold;

Fig. 3 is an end elevation of the machine in the position it occupies at the conclusion of the pressing operation; and

Fig. 1 is a perspective view of the completed mold.

Like numerals indicate like parts in each of the several views.

Referring to the accompanyingdrawings, I provide a suitable bottom base block 1 having a tapering approximately semi-cylim cal upstanding form extending longitudinally of the central portion'of the base 1 over which the sheet of metal 9 is pressed to form the mold desired. I provide upper blocks 3 and 5 of similar shape and having recessed portion 7 corresponding in shapewith the tapering upstanding mold form 2 and adapted to seat thereover. I provide a suitable number of hinges 4 by means of which the block 3 is hinge d to the base 1, and I also provide a suitable number of hinges 6 by means of which the upper block 5 is hinged to the upper block 3, as shown in Fi 2 and 3. I also provide a suitable operating handle 8 aflixed to block for manually operating the device. 7 I also provide suitable means for engaging one edge of the sheet of metal 9, such as a pair of spaced metal plates 10 afiixed to the bottom surface of upper block 3 and held in spaced relation by suitable spacing members 12. I also provide a metal plate 13 on the upper surface of base block 1, shown metal block in which position the metal plate 9 is pressed 5 into an approximately semi-cylindrical shape in cross-section, with opposite laterally extending flanges 11, as shown in Fig. 4.

1927. Serial No. 195,531.

What I claim is r p 1. In a device of the class described, an elongated base block having an upstanding approximately semi-cylindrical tapering form, a pair of elongated upper blocks recessed to form a semi-cylindrical tapering recess substantially corresponding with the upstanding form of the base block, one of the upper blocks being hingedly mounted to the base block, a handle attached to the hinged blocks for actuating same, and means carried by one of the blocks for holding the edge of a sheet of metal which is to be pressed into the desired shape to form a mold of the charactor described.

2. In a machine of the classdescribed, the combination of a base block having an upstanding semi cylindrical form extending longitudinally of the base block, a pair of upper blocks having a longitudinally extend- I ing recess corresponding in shape with the upstanding form of the base block, one of gree of swinging movement relative to each other, means carried by said upper blocks for manually opera-ting same, and means a'tlixed to the innermost upper block to receive the edge o1 a sheet of metal to be pressed into the desired form to produce the mold.

3. In a machine of the class described, the combination of a base block having an upstanding semicylindrical form extending longitudinally of the base block, a pair of upper blocks having a longitudinally extend.- ing recess corresponding in shape with the upstanding form of the base block, one of said blocks being hingedly attached to the base block, the said upper blocks being hingedly connected to permit a limited degree of swinging movement relative to each other, means carried by said upper blocks for manually operating same, a pair of metal plates aii'ixed in spaced relation to the lower surface oi? one of the hinged upper blocks to receive and hold the edge of a sheet of metal while 7 it is being pressed into the desired shape over the form, substantially as shown.
